Should I get the Pre-approved Airtel Axis Card? (I'm not into Airtel ecosystem)

I currently hold Flipkart Axis and Neo with combined limit of ₹95k. While checking for limit increase in the app, noticed that Axis is offering Airtel with 9 other cards.

However, I’m not part of the Airtel ecosystem at all. I have 4 Jio SIMs in the family for mobile services and ACT Broadband for internet.

Do we still get cashback for paying Non-Airtel utility bills and recharges via Thanks app?
